Australia has had a rash of wildfires caused by unseasonably hot and dry weather. Scientists say the risk of fires is growing with climate change, but the country's new prime minister says they're just a normal part of life down under.

Climate change will increasingly put food supplies at risk, while opening up some new areas to agriculture. That's the gist of a leaked new draft UN report on climate change impacts. Host Marco Werman talks about the frontiers of our changing food supply with report co-author David Lobell of Stanford University.

Imagine standing on an exposed steel girder of a bridge 440 feet above Sydney Harbour to get a spectacular view of sunrise over the Pacific. Phil Roach, a climb leader with BridgeClimb Sydney, takes tourists up for the bird's eye view a few times every day.

A flag is usually a symbol of national pride. But not necessarily in New Zealand, where voters will get to decide whether to ditch the design that dates to colonial times. And for some reason a Cadillac ad that lauds America's work ethic and paints Europeans as slackers just rubs some Europeans the wrong way. All that and more, in today's Global Scan.

Early Thursday morning in Australia, officials revealed what was said to be the first good lead in recent days around missing Malaysia Airlines Flight 370. But a day full of searching ended without a breakthrough, yet.
